When buying a padlock, you've traditionally had two options: buy a key-based lock and risk losing the key, or buy a combination lock, and hope you can remember the code. Both could potentially end with you wielding bolt cutters. Now, the Noke Bluetooth Padlock gives you a third option. Powered by Bluetooth 4.0, this smart padlock pairs with your phone, letting you open it simply by pressing the shackle — it will automatically sense your phone and unlock. And should your phone die, you can create a custom access code that has you press the shackle in a certain pattern to unlock. It's just one less thing to worry about.
